GeForce 930M vs GeForce 9500 GT 1GB GDDR3

Intro

The GeForce 930M features a core clock speed of 928 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit memory bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Compare those specs to the GeForce 9500 GT 1GB GDDR3, which has a core clock speed of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also uses a 128-bit bus, and makes use of a 55 nm design. It is made up of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 9500 GT 1GB GDDR3, in theory, should be quite a bit faster than the GeForce 930M overall. (explain)

GeForce 9500 GT 1GB GDDR3 25600 MB/sec
GeForce 930M 14400 MB/sec
Difference: 11200 (78%)

Texel Rate

The GeForce 930M is quite a bit (approximately 153%) faster with regards to texture filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce 930M 22272 Mtexels/sec
GeForce 9500 GT 1GB GDDR3 8800 Mtexels/sec
Difference: 13472 (153%)

Pixel Rate

The GeForce 930M is a lot (about 69%) more effective at AA than the GeForce 9500 GT 1GB GDDR3, and also capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce 930M 7424 Mpixels/sec
GeForce 9500 GT 1GB GDDR3 4400 Mpixels/sec
Difference: 3024 (69%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
